How to make a Post request to an API using Google Colab

Question

I need to make the following POST request using Google Colab:

POST https://http.msging.net/commands HTTP/1.1
Content-Type: application/json 
Authorization: Key YOUR_TOKEN 

{ 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "postmaster@wa.gw.msging.net", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

I have tried:

import requests
import re

YOUR_TOKEN = "mytoken"

data = { 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "postmaster@wa.gw.msging.net", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

headers = {
  "Content-Type": "application/json", 
  "Authorization": YOUR_TOKEN 
}
response = requests.post('https://http.msging.net/commands', headers=headers, data=data)

print(response)

For which I get:

<Response [400]>

I also tried:

import requests
import re

YOUR_TOKEN = "Key cHJvY29ycG9lc3RldGljYWF2YW5jYWRhMTg6cEFBSXFuYTZOR1FFWnpydFltTlo="

data = { 
"id": "a456-42665544000-0123e4567-e89b-12d3", 
"to": "postmaster@wa.gw.msging.net", 
"method": "get", 
"uri": "lime://wa.gw.msging.net/accounts/+55115555555" 
}

headers = {
  "Content-Type": "application/json", 
  "Authorization": YOUR_TOKEN 
}
response = requests.post('https://http.msging.net/commands HTTP/1.1', headers=headers, data=data)

print(response)

For which I get:

<Response [404]>

How do I get this request using Google Colab?

Here is the documentation, it does not provide examples. Just the requests.

No, because, even if it works outside Colab, I would not be able to implement it. I am constricted by the use of Colab. — user3347814, Mar 26 '22 at 18:42
@user3347814 then it is not colab specific issue, make sure your api call work first with `curl` command — gftea, Mar 27 '22 at 09:34

You get a 400 Bad Request error, as - although you set the Content-Type header to application/json - you do not send JSON-encoded data.

As per Python requests documentation, when sending JSON data, you need to either use the data parameter and pass a JSON-encoded string, as well as manually set the Content-Type header to application/json:

payload = {'some': 'data'}
r = requests.post(url, data=json.dumps(payload), headers={"Content-Type": "application/json"})

or, if you don't want to encode the dict yourself, use the json parameter, and Python requests will automatically encode it for you, as well as set the Content-Type header to application/json:

r = requests.post(url, json=payload)

You would still need to add your TOKEN key to the Authorization header, as you already do.

Given the documentation, could you please provide an example with the specifics of this API? — user3347814, Mar 28 '22 at 13:25
The HTTP/1.1 would be included some where or I can just ignore it? — user3347814, Mar 28 '22 at 14:55
